And that is what makes it
possibly unsafe to do.
Not that much is removed in this case, but this can compromise the wheel, its quality and load bearing ... potentially sufficiently that I would
rather buy a set of aftermarket wheels with the quality, correct sizes and bolt pattern for a Nissan/Infiniti (if I was in the market to change wheels).
BTW, "spacers are evil" is another thing that I believe in (although not an original comment from me - came from a former Tire Rack expert who used to post in our Wheels forum).

YMMV, of course ... I simply prefer not to add any extra rotational weight to my car wheels.
Particularly if the spacers are not hub-centric - these can move a bit (since they are effectively only centered by the lug bolts and nuts) and cause unbalance.
Of course, please do remember I tend to stick with OEM wheels too (since I'd rather use my money for performance enhancing purposes for my car - like great tires!), so feel free to take my comments with a grain of "why" salt.
